To evaluate the effectiveness of different, grower-chosen strategies to apply liquid nitrogen.
In all three trials there was no statistically significant yield response to additional post-emergent liquid nitrogen. Given the below average rainfall experienced in the district in this season, this result is probably not unexpected.
For further comments please see the attached trial report.
